Locomotives listed in the above roster typically featured some type of large OLS emblem or banner. Additionally, several railroads applied
small (6" x 6") OLS "stickers" to a select number of locomotives. Those railroads included: Central Oregon & Pacific, New England Central,
Rail America (and subsidiaries) and Vermont Railway.

In 1985, Baltimore & Ohio repainted ex-C&O NW2 5065 in a green and white livery, with large white lettering to remind employees of "Safety First."
